The A3 uses MIPS technology to offer the best protection. The A3 also extends lower than previous TLD helmets, to offer the best lower head coverage.
Every detail of the TLD A3 has been obsessed over. The adjustable visor has goggle storage and attaches in three positions with magnets, so it is easy to move as well as avoiding any small parts breaking. The helmet closes with a V2 Fidlock-Magnetic Buckle for easy on and off. TLD has also made sure the helmet works with a vast array of optics making it a great choice for riders, regardless of eyewear choice.

How to measure
To find the circumference of your head, place a tape measure in the centre of your forehead, wrap it around above your ears and around the back of your head. If there's a slight difference between two different sizes, always go for the tighter size.
Once you know the circumference of your head, see the available sizes shown on the product and select the appropriate one.
The majority of cycling helmets have some form of adjustment for size, usually in the form of a ratchet adjuster to tighten or loosen the straps, some helmets will also come with different thickness pads to further customise the fit.
